Teralytic

Wireless soil probe reading NPK at three depths, sold as an annual per-probe service rather than a sensor

As of 1 September 2026, Teralytic's pricing is not published; the vendor quotes on request. A 26-sensor soil probe that reports nitrogen, phosphorus and potassium wirelessly, which almost nothing else does in-field. Softwr lists it under Agriculture. Teralytic is made by Teralytic, Inc., available on Web, iOS, Android.

Overview

What Teralytic does

Teralytic makes a wireless in-ground soil probe carrying 26 sensors, including what it describes as the first wireless NPK sensor. It reports moisture, salinity and NPK at three depths plus aeration, respiration, air temperature, light and humidity, uploading over a long-range radio network to a cloud analytics platform. The value proposition is continuous soil chemistry rather than the point-in-time snapshot a lab soil test gives, which is what makes nutrient timing decisions possible during a season rather than between them. The commercial model is service rather than product: probes are charged up front with an annual per-probe subscription covering hardware, connectivity, software and analytics. Publicly reported figures have moved over the years, from around 500 US dollars per probe per year in early deployments to a roughly 200 dollar probe with a 300 dollar annual subscription later, and the company does not publish a current rate card. Nothing works without the subscription, so a probe in the ground is an annuity, not an asset. Buyers are research programmes, large row-crop operations testing variable-rate nutrient timing, and specialty growers where a nutrient error is expensive. The decisive caution is scale: Teralytic is a very small company, reported at around six employees across two continents. In-field NPK sensing is technically contested and the analytics depend on continued calibration work, so buying here is a bet on a small team staying funded for the life of the probes you bury.

What people use it for

A research trial that needs continuous nitrogen readings between sampling dates rather than two lab tests a season
A vegetable grower on sandy ground where leaching after rain makes a fortnightly lab test worthless
An almond or vine operation tracking salinity build-up under drip irrigation
An agronomist validating a variable-rate nitrogen prescription against in-ground readings

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Teralytic.

The company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
No current pricing is published and reported figures have moved between roughly 300 and 500 US dollars per probe per year, so a buyer cannot model the cost of a hundred-probe deployment without a quote.
The subscription is mandatory for the probe to report at all, so the up-front hardware payment buys nothing durable and a lapsed account means a field full of dead instruments.
In-field NPK sensing is scientifically contested and readings need interpretation against soil type and calibration, so agronomists will not treat the numbers as interchangeable with a lab test and many will insist on both.
Spatial coverage is the unsolved problem: a probe measures one point, soil varies over metres, and covering a field properly multiplies both the hardware and the annual subscription by the number of zones you care about.

Answered, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Can I buy the probe without a subscription?

No. The probe reports through Teralytic’s network into its cloud, and without an active subscription it does not deliver data.

Does it replace lab soil tests?

No. It gives continuous in-season trend data. Most agronomists will still want lab results for absolute nutrient values and for compliance records.

How much does it cost?

Teralytic does not publish current pricing. Reported figures have ranged from roughly 300 to 500 US dollars per probe per year including hardware and connectivity.

How many probes does a field need?

That depends on soil variability. One probe represents one point, so a field with several distinct soil zones needs one per zone to be meaningful.
